Specification of Letters Patent. i

Patented April 14, 1908.

Application filed February 11, 1903. Serial No. 142,867.

To all whom it may concern:

Be it known that I, AUBIN M. CHASE, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Plow, of whichvthe following is a specilicationl My invention` has for its object the production of a plow, which is particularly' simple and 5 are Vertical sectional views taken, re-- spectivly, on lines A A, B B and C C, Fig. 1.

The illustrated exompliiication of my invention is what is known as a gang-disk plow, but I do not limit this invention to either a disk plow or a gang plow'. Said gang plow consists, essentially, of a frame, a plurality of earth turning members or elements as the disk plows proper, 1 Q-,a land-wheel 3, front and rear furrow-wheels el 5 and means for raising and-lowering the frame relatively to.

the land-wheel and the front furrow-wheel, and holding said frame in its adjusted position. The traine consists of a main member 6 and a detachable memberj; the member 6 being formed with a forward extension 8, to which the draft-animals are connected, and with a rear laterally-extending fixed arm 9. The disk or lin the arm 9, an a scraper 10 for said disk for plow is suitably supported on the arm 9. Said detachable frame-member 7 is formed at its front end with a laterally-extending arm 11 having an upturned pivotal po* tion 12, which may be journaled at will in lier one of two pivot-bearings 13 14, provided side'by side at the rear lend of the frame-member 6. The rear end of the detachable Jframe-member 7 is of' substantially the same construction as the corresponding end of the frameniember 6, being provided at one side with pivot-bearings 13 14, and at the other side withv a fixed arniQ, which is equipped with a bearing for the disk or plow-pro per 2 and su 'V ports a corresponding scraper 1:11. lt will 'e (plow-proper 1 is journaled readily understood that additional framemembers 7 `may be coupled in a chain, one in front of the other, to the illustrated member 7.

The land-wheel?) is ofany desirable forni,

size and construction, being here shown as journaled in the rear end of a movable arm 15, having its frontend loosely mounted on a spindle or arm 16 projecting laterally from t erear end of the frame-member 6. The arm 15 is rocked on the spindle or arin l by any suitable means, as an upwardly extending lever'17, and is held in its adjusted posi-` tion by a toothed segment 1S lixcd to said spindle or arm 16, and a locking member 1S() supported by said lever 17 and cooperating wit-h the segment 1S. As the arm 15 is rocked on the spindle 16, the frame raised or lowered relatively to the rear cn-l ol the arm 15 and the land-wheel 3.

In the preferable construction ol' my plow,

1 bearing 21 and is connected to tlnA traino ol` Lthe plow by means presently dosrrdiod.

4 is in its position When the furrow-Whoo assumed during the turning ol' the lui-row, the lower portion, or. tread, of its periphery is at the inner side ol a vertical plano indicated by the line 24, extending :tln'ough'ilre substantially vertical pivot 2O ol ihrarin'l parallel to the line of drall, (or in other words, at the inner side of the pivot or axis for the furrow-wheel 4) and the l'ront portion of said wheel 4 is generally extended in @id-- Vance of the pivot 20. The lnirow-.\ 'liool l, arranged as shown and described, readily swings inwardly on its axis, as indiratrd io dotted lines, Fig. 1, for facilitating iurnin of the plow t-o the right, and when the plow is again drawn forwardly swings in a reverso direction or back to the position indicated by full lines in Vthe drawing. "lhe draft oi"v the plow, when moving forwardly, tends to hold the arm 19 in engagement with die sto 23 and thus holds the plow-proper substantially parallel to the lin(` of dral't'in the normal use of the plow and causes the plow to more in a line substantially parallel with. the furrow previously turned. Said stop 23 thus limits the outward swinging of the urrow-wheel on the substantially vertical axis thereof." By arran ing the pivot of the arm 19 at the the front portion of the furrow-wheel 4 and in advance of the bearing 33 of the su port 22, the amount of s ace required for t 'e swinging movement of t e furrow-wheel 4 1s reduced to a minimum, and it is ossible to sup ort said furrow-wheel so as to e capable of tlie desired movement on. its substantially vertical'axis at one side of the frame-member 6 and infront of the plow-proper 1, without lengthening the frame or re uiring s ecial construction thereof. stood, however, that the arm 19 may be of sufficient le gth so that the front portion of the furrow-w pivot 20.

It is sometimes desirable to lock the furrow-wheel` 4 from movement on its substantially vertical axis, as when the plow is used on a side hill. This result may be accomplished by any suitable means, ,as a pin or locking member 25, removably arranged in apertures in ears or projections, on the arm 19 and the support 22, and connected to the support 22 by a chain in order that it may be present for use when needed.

As here illustrated, the means for raising and lowering the frame relatively to the front furrow-wheel 4 and holding the same in its adjusted position, consists of a shaft 26, a lever 27 and a locking member 28. The shaft 26 is formed with a crank-arm 29 and with front and rear pivotalportions 30 3 1, respectively, journaled in a bearing 32 provided on the frame-member 6, and in the bearing 33 of the su port22. The lever 27 is pivot'ed at one end) at 34 to an arm rising from the frame-member 6, is pivoted at 35 to a notched or toothed arm 36 rising from the support 22, and is provided with a handengaging portion at its other end. Said shaft 26 and lever 27 form connecting members between the frame and the support 22, and move relatively to said frame and su port when etici-tin(y vertical adjustment o the frame relative y to the furrow-wheel 4. It will be noted, that the distance between the pivots 34 35 is substantially the same as the distance between4 the pivotal portions 30 31 of theshaft 26, and that therefore, as the frame is raised or lowered relatively to the support 22 no material variation in the line ieel 4 will be at the rear of the of direction of the pivot-bearing 21 is effected,

and consequently, variation in the operation of the front furrow-wheel 4 is avoided. The locking member 23 is sup orted by the lever 27 and is movable into an( out of the notches in the arm 36. When said locking member 'is in operative position, the shaft 26 and the lever 27 are prevented from movement relatively to the support 22, and the frame of the Vlocate plow" is firmly' relatively to the support 22.

The bearing 32 is usually movable laterally relatively to the frame-member 6 and is held in its adjusted position by any desirable kthe rear end of an arm having a substantially upright pivot38, detachably journaled in a pivot-bearing 39, provided in a part 40 which may to the rear ends of the frame-members 6 7, and isprovided with a stopfll for limiting the turning of said furrow-wheel on the pivot 38 to its position assumed during the turning of the furrow. Said pivot 38 (or in other words the axis of the furrow-wheel 5) is obviously arranged at the rear of the front portion of the rear plow-proper, and said furrow-Wheel is free to swing on the pivot 33 inwardly 'behind the' rear plowprper, as indicated by dotted lines.

be removably secured had in its adjusted. pagine-1i' he construction and operation of my plow will now be readily understood upon reference to the foregoing description and the accompanying drawing, and it will be apparent that more or less change may bef made therein, without spirit of my invention.

Having thus fully described Amy tion, what I claim as new and desire cure by Letters Patent, is1- 1. In a plow, a frame, an earth-turnn element, a trailing non-,tongue-controlle caster-wheel arranged in advance, and to the furrow-side of the earth-turning element, the advance ortion thereof extending in departing from the invento sefront of the pivot of the caster-Wheel, said caster-wheel arranged in advance, and to the' furrow-side of the advance front of the caster-wheel being staggered so that its lower (portion in contact with the ground, is

at the inner side of a vertical plane passing through the ivot of the caster,- wheel parallel to the line of draft, a fixed stop on the frame for limiting the outward the, earth-turning element, portion the'eof extending in of draft in the pivot'of the caster-wheel, saidv swinging movement of the casterzwheel, and thereby holding said wheel substantially parallel to the line of draft, and means for raising and lowering the frame relatively to the caster-wheel'without materially affecting the relative position of the frame and said pivot of the caster-wheel, substantially as and for the purpose specified.

3. In a plow, frame, an earth-turning element, a trailing non-tongue-controlled caster-wheel arranged in advance, and to the furrow-side of the earth-turning element, said caster-wheel being staggered so that its lower portion, in contactwith theground, is located at the inner side of a vertical plane passing through the pivot of the caster` wheel parallel to the line of draft, said casterwheel being free to swing inwardly about the axis of its pivot relatively to the frame as the plow is turned to the ri ht, a fixed stop on the frame for limiting tie outward swinging of the caster-wheel relatively to the frame, and a rear trailing caster-wheel arranged at the rear of the earth-turning element and movable independently of the first-mentioned caster-wheel, substantially as and for the purpose set forth.

4. In a plow, a frame having a bearing, an earth-turning element, asupport having a substantially upright pivot-bearing, a stop at the rear of th(l pivot-hearing, and a second pivot-bearing at the rear of the lirst-1nentioned pivot-bearing, a shaft formed with a crank-arm and with front and rear substantially horizontal. pivotal portions jourialed, respectively, in the bearing of the arm carrying the furrow-wheel at its rear end and having its front end provided with Ya substantially upright pivot journaled in the -first mentioned pivot bearing of the support, said arm being movable about the axis of its L vot to perrnit the furrow-wheel to swing inwardly, and coacting with the fixed stop of the support to limit the outward swinging of said furrow-wheel, and a rear trailing caster-wheel arranged at the rear of the earth-turning element and movable independently of the first-mentioned caster-wheel, substantially as and for the purpose specified.

l In testimony whereof, I have hereunto signed my naine in the. presence of two attesting witnesses, at Syracuse.,A in the county of Onondaga, in the State of New York, this 19th da)v of January, 1903.
